Investigators said they were called to a residence in the 5700 block of Terrace Trail (in the municipality of Sansom Park) at 12:17 a.m. A man told police he returned home to find his girlfriend, identified as 46-year-old Rhonda Waits, on the tanning bed and unresponsive.

Authorities told the station there were no signs of trauma.

The Tarrant County medical examiner has not ruled on a cause of death.

WFAA published an update to the story on Monday:

In a statement released Monday, authorities reported that the tanning bed was not on at the time Waits was found. However, the tanning bed does have a timer that turns the machine off when the time expires.
